vTo all whom 'it may concern:

Be it knownthat We, WALLACE I. STIMP- v son and GEORGE B; AMBLER, citizens of the `.finding means, suita United States', and residents oflMilford, county of Worcester, and South Framingham, county of Middlesex, in the State of .Massachusetts have invented an Improvement in Automatic Filling-Replenishing Looms, of which the following deseri tion, in connection with the accompanying c rawing, is a specification, like letters on the drawing re resenting like parts.

llhis invention relates to looms provided with mechanism to automatically replenish the running filling, and is illustrated in connection witha loom of the Northrop type,

such for instance as forms the subject-matter automatic filling-replenishing loom it is imortant that the ick in which new filling is st laid after rep enishment following filling failure be the same one in which the failure of the old fillin took place, so that there shall be no mis-pii, or empty pick, in the cloth.

The present invention is applied to a threeharness loom and is so arranged and constructed that when the filling breaks when traveling-in one direction the filling will be automatically replenished and the new filling will be laid in the same shed of the cycle as If the fills'ite direction the loom is stopped automatically, giving the weaver an opportunity to match the pick in usual manner.

The invention is herein shown as a plied toa loom equipped with a filling fee er, so thatwhen, the running filling is exhausted to a .predetermined lextent the feeler will effect replenishment, making a perfect joining in the cloth.

In the present embodiment of the invention the loom is provided with two filling-'detectors or forks,the detector at the shipper side of the loom being arranged to release the shipper and effect loom stoppage when filling absence is detected by such detector. The other detector, at the replenishing side of the loom, is arranged to cause filling re lenishment on the second pick after such c etector detects filling absence, s'o that the new filling is laid in the same shed of the 3-shed cycle as that in which the old filling failed7 thereby matching the ick automatically. Such construction is Va vantageous over the ordinary feelerl and double-detector style of loom in which both detectors act to stop the loom upon detection of filling absence, in that in the present case the loom continues to run when the filling breaks when laid in one direction` and is stopped only when the break occurs When laid in the opposite direction. This permits a Weaver to run a greater number of' looms.

It is a curious fact that in the actual practice when the filling breaks the right-hand detector, or that one at the replenishing side of the loom, will on the average detect first considerably more than half the time. This is believed to be vdue to the fact that on the replenishing side the shuttle-eye is further from the edge of the cloth by almost the length of the shuttle .than it is on the opposite or shipper side, and there are more chances for the broken filling to tilt the fork improperly at the shipper side than at the replenishing side. That is, if the broken filling' i end trails after the shuttle going to the shipper side there `-is a tendency to engage and tilt thefork at such side, but when the shuttle is going to the replenishing side the eyeend leads and the'broken end extends such a short distance behind the shuttle that it practically never-tilts the adjacent fork, and the latter thereupon detects filling absence.

The various novel features of the invention will be fully described in the subjoined specification and particularly pointed out in t e following claims.

and through the mechanism previously explained causes filling replenishment at the proper time to match. the pick with the new filling., Suitablesprings s and s effect the return movement of the fork-slides f2 and g2 respectively. The opening 4 in the latch?, is madeflarge enough to-permit lthe lifting of the latchwithout restraint from the end 34 of the transmitter, and the cam 10 islmade yielding so that as the'bunter 7-1 moves-` the latch forward theV sli .ht depression of the rear end ofthe latch will not cause any strain or breakage, the cam Igiving-to the downward push of the follower 8. Said follower is provided with a toe 11 whichvprojects beneath a stop lug`12 on the latch, F ig; 4, preventing any turning of the follower on the'forward movement ofthe latch, while follower to lift over the front end of the cam 10as the latchreturns to normal position.

So far as the operation by the feeler is con cerned it is sufficient to state that when the predetermined filling exhaustion is l reached the transmitter 35 is tilted, andthe end 34 lifts the latch -tootlr into the ath ofthe bunter 7, so that the shaft d wi lbe turned and filling replenished when the shuttle is I boxed at B, lig; 1. No arrest oftakeup is effected, as none is required, the fresh filling being laid before the old. filling runsout.

It is necessary now todescri'be the manner` in which loomstoppage is effectedwhen filling absence is first detected by the detector usual holding notch in the plate Nx by movement of the knock-off lever nx, fulcrumed'on the loomfr'ame at n and having'v one arm ex tended at n .to a point near the slide f2. A

controller 16, separately shownin-Fig, is

pivotally mounted at 17 on the slide fzand has a forwardly extended toe 18 normally positioned back of the end n ofthearm of" the knock-ofi lever,lateral lugs 19; on the controller resting on the. top of the slide.` Said controller is also provided with anupf right web 2O supporting an elongated, lateral rib or shelf- 21 which overhangs` andV rests u on a stud 22 projecting from the inner side of the latch 3, the shelf inclining-downward and forward, as shown. y f

,detected by the-fork fx, the shuttle going totheleft, `the forkis not tilted and its slide] x is movedfor-r ward by the actuator W, andthe toe 1.8-.of the controller 16 is brought against the extension n; turning` the knock-offlever to release theshipper Ny and'effectloomstoppage At thelsametime'the arm d'is swung .forward A toarrest the operation .of the take-u kmech-` anism, the weaver matching. the picffinpthe permitting the The shipper N Fig. 1, is releasedfromfits l actingithrough the extension 13 v' usual mannerafter the loom has stopped and the broken 'filling has been pieced up. i

It will be remembered that the slide f2 is moved forward on the shuttle fiight to the left after filling absence has been fork gx, but at such time the latch 3 has been elevated and the stud 22 on said latch raises the shelf 21fso that the toe 18 of the control-r Wvhile'thedetector gx detects filling absence a second time in the' casewhere absencejis first, detectedA on the shuttle flight to the right the `second detecting action will not cause a second and needless actuation f the replenishing mechanism, because the rockshaft d is then held in position by the actu-` `ator WV and intervening devices to effect filling replenishment, and the 'short forward stroke ofthe slide g2 will not be enough to co-y operate withthe arm d3.

L Thiswillibe manifest from the foregoing descriptionand an l In l'the threel harnesses are indicated i at I', II and III to form the three-shed cycle for which this mechanism herein described is;

particularly adapted, the shedding devices per` se formin no part of this invention vand eing of any esired character to vperform the requisite work. It will be seen that the function ofone detector is to effect loom stoppage promptly when it detects fillingv absence on they shuttle'fiig'ht towardthe side ofthe:

loom at which said detector is located,l while the other detector eHects filling replenishment when filling absence is -tected by it, but such replenishment is effected independently of the first named detector. Herein thestopping detectoris lof cated adjacent the shi per side of the loom vand the replenishing etector adjacent the Lreplenishing side of the loom, detecting action by such klatter detecton causing a de- .layed or retarded'operation of the replenishing` mechanism until the shuttle at the replenishing sider after deteef-ion of. fillingfabsence. The positionof Athe controller on the slide of tector, determines whether outwari move- --ment of such slide willstoprthe loom 'or replenish filling, and the positionl ofthe ,oon-l l troller is governed by the latcli'3, as1v'illcbe manifest.
